I think she's good compared to how most female characters are portrayed in lots of yaoi mangas (like that short haired one gossiping on Mafuyu). Tbh I would be fine if Kaji were to end up with her or the long haired guy, we don't even know if she knows there's something between the two so it's not like she's trying to take him away from the long haired guy. It's pretty normal for someone to want to spend time with their crush if they're close.
The only good girl is the sister lol I like her
